  • supposed to have a fundamental role in the regulation of smooth muscle tone in blood vessels and lung (
  • may influence sperm motility
  • calcium (Ca2+) and magnesium (Mg2+) conducting channel, during proliferation of human osteoblasts
  • its activation is sufficient to induce keratinocyte differentiation similar to the physiological stimulus [Ca2+]
  • playing an essential role for proper regulation of podocyte structure and function, by its channel activity at the slit diaphragm
  • Ca2+-permeable channel, activation of which is linked to a G protein-coupled receptor or receptor tyrosine kinase signaling pathway
  • playing a unique and indispensable role in acute hypoxic pulmonary vasoconstriction
  • required for BDNF-mediated neuronal protection and protects cerebellar granule neurons against serum deprivation
  • might act as an important mediator for sensing the extracellular signals that affect synaptic and behavioral plasticity
  • involvement of TRPC6-mediated Ca2+ entry in the RHOA-dependent regulation of actin cytoskeleton has been demonstrated in endothelial cells and kidney podocytes
  • playing an essential role for angiotensin II-induced cardiac hypertrophy
  • contributes to the Ca(2+) leak of human erythrocytes
  • promotes hippocampal neuron dendritic growth
  • regulates TRPC3 activation by erythropoietin by modulation of signaling mechanisms, including reduced interaction of TRPC6 with phospholipase C gamma and Epo-R
  • may be involved in VEGF-mediated angiogenesis
  • participates both in cacapitative Ca2+ entry and non capacitative Ca2+ entry through its interaction with the Orai-STIM1 complex or TRPC3 respectively
  • invovled in the development of gastric cancers through the regulation of Ca2+ elevation which is essential for G2/M transition
  • necessary mediator of pathologic cardiac hypertrophy, in part through a calcineurin/NFAT signaling pathway
  • TRPC5 and TRPC6 are antagonistic regulators of actin remodeling and cell motility in fibroblasts and kidney podocytes
  • TRPC5 and TRPC6 channels are now known as the Ca(2+) influx pathways for nonselective, cationic current in podocytes
  • upregulation of TRPC6 is involved in the Ca2+ signaling and actin assembly in human mesangial cells (MCs) after chronic hypoxia
  • role of TRPC6 in actin assembly and reorganization in response to chronic hypoxia
  • TRPC3 and TRPC6 are thus required for the normal function of cells involved in touch and hearing, and are potential components of mechanotransducing complexes
  • dual and context dependent role of TRPC6 in podocytes where acute activation protects from complement-mediated damage, but chronic overactivation leads to focal segmental glomerulosclerosis
  • is the endothelial calcium channel that regulates leukocyte transendothelial migration during the inflammatory response
  • TRPC6 channel translocation into phagosomal membrane augments phagosomal function
  • may protect renal ischemia-reperfusion injury through inhibiting necroptosis of renal tubular epithelial cells
  • is emerging as a functional element for the control of calcium currents in immune-committed cells and target tissues
  • is important in glomerular epithelial cells or podocytes for the process of glomerular filtration
  • TRPC6 plays a crucial role in the development of kidney injuries by inducing podocyte injury, maybe via its role in the immune system

  • phospholipase C (PLC)-gamma1 and cytoplasmic domain of nephrin (
  • insulin increases generation of ROS in part through activation of NADPH oxidases, and this step contributes to modulation of podocyte TRPC6 channels
  • PI3K/PTEN pathway plays an important role in the translocation of TRPC6 to the plasma membrane and may thus have a significant impact on Ca2+ signaling in cells that endogenously express TRPC6
  • SNF8 interacts with TRPC6, binding to the amino-terminal cytoplasmic domain of the channel
  • TRPC6 down-regulation could contribute to the antiproteinuric effect of vitamin D
  • involvement of three basic residues in the integrative overlapping binding site for S100A1 on the C tail of TRPC6
  • function of NOD2 for the regulation of TRPC6 channels, suggesting that TRPC6-dependent Ca(2+) signaling is one of the critical signal transduction pathways that links innate immunity mediator NOD2 to podocyte injury
  • PRKG1 is a potent negative modulator of cardiac systolic mechanosignaling that requires TRPC6 as the target effector
  • redundant role of PLCE1-mediated TRPC6 activation at least in podocytes
  • locally generated SDC4 may play a role in regulating TRPC6 channels, and may contribute to glomerular pathology
  • evidence for a role of immunophilins, including FKBP3 and FKBP8, in Non-capacitative calcium entry (NCCE) mediated by TRPC6
  • lysophosphatidylcholine (lysoPC) induces CALM1 phosphorylation at Tyr(99) by a Src family kinase and phosphorylated CALM1 activates PI3K to produce PIP3, which promotes TRPC6 translocation to the cell membrane
  • lipid oxidation products, including lysophosphatidylcholine (lysoPC), activate canonical TRPC6 channels, and the subsequent increase in intracellular Ca2+ leads to TRPC5 activation
